Abstract: 455,884. Sewing-machines. MOUSSET, A. G., 46, Rue Jeanne d'Arc, St. MandÚ, Seine, France. Dec. 7, 1935, Nos. 33980 and 33981. Convention dates, April 8 and Oct. 17. [Class 112] In a shoe-stitching machine with a segmental awl and segmental needle, the work being fed by the awl, the awl and its control system are carried by a lever pivoted on the frame and displaced by a vertical cam plate to bring the awl under the needle. The needle - carrying segment is also actuated by a pivoted lever moved by the cam plate. Chain stitching. Shoes are stitched by a segmental needle 38 carried in a toothed segment 37 operated by a toothed arc 36 on a lever 29 pivoted to a bellcrank lever 30 and operated by a roller 34 tracking in a groove 35 in the main cam 1. Pivoted to the other arm of the bellcrank lever 30 is a second arm 28 with a roller 32 tracking a groove 33 in the cam parallel with the groove 35 so that the levers 28, 29 move in unison. The lever 28 has a dog 46 co-operating with a lever 45 to lift the presser foot 43 from the work when the needle is retracted to permit feeding. A lever 55 pivoted at 54 following a cam face in the main cam rocks the lever 45, the amount of rocking being adjustable by a rack 48 and pawl 58. The needle is barbed and a looper 23 moved in a bight of thread on the barb when the needle has pierced the work. The looper is pivoted on the end of a lever 19 pivoted to a lever 3 at 20 and rocked by a roller 21 following a cam track 22 on the main cam 1. A stop 27 engages a heel 26 on the looper during its rising motion to give it a sideways movement. Feed by awl. The segmental awl 13 is mounted on a toothed segment 12 driven by a toothed arc 16 on a lever 15 pivoted to the lever 3 at 14 and rocked by a roller 17 tracking a groove 18 in the main cam 1. This causes the awl to penetrate the work. While in the work, the awl is moved sideways to effect the feed by a roller 6 on the lever 3, which is pivoted to the frame 2 at 4, engaging a cam projection 3<1> on the cam 1, Fig. 7. When the awl is withdrawn from the work, a spring 7 returns the lever 3 and the length of the feed is determined by a screwed pin 8. When the awl is retracted, the needle enters the hole formed by it. Thread waxing. The thread passes from a supply 60 through a wax pot 62 to a roller 63. Thread tension devices. The needle segment carries a needle guide 65 and a disc 64 with a resilient collar and a spring 67 to apply tension to the thread. Lock stitching by rotary hooks. Instead of chain stitching, lock stitches are made by the aid of a hook 71 carrying the bobbin for the under thread and rotated on the shaft 72 twice for each needle reciprocation. A loop spreader 83 for widening the needle loop is also provided.

In a fluid-tight coupling of the kind in which a bush 16, Fig. 1, of resilient impervious material is located between each of two circular, oval or flattened pipes 1, 2 and an enclosing sleeve 5, 3, 4, each bush is produced by winding a tape or cord of mouldable material around the corresponding pipe end until it almost fits the sleeve and causing the windings to coalesce into a coherent mass in non-adhesive contact with the pipe and sleeve by applying axial pressure, with heat if desired, as by tightening bolts 10 to draw in sleeve ends 4, 5. The bush material may be rubber, applied unvulcanized and heated after compression to vulcanize it and render it resilient. Alternatively the bush may be of a thermoplastic material, such as synthetic rubber or plasticized polyvinyl chloride, which is heated during compression to render it temporarily plastic instead of elastic. Spirally wound type may be used which is embossed or having part-spherical depressions on one surface which form voids 18, Fig. 4, in the compressed bush 16. With pipes corrugated axially by circumferential troughs the bush may be formed from touching turns of a single helical winding of solid or hollow cord or two superposed helical windings of solid cord.
